Re: Wrong answer

There is no good place to put a staple in your body... but the worst I had was roofing and the other guy had is trigger wired back and the gun slid down the roof and hit my knee and went off. I remember thiking, "it's a good thing that didn't go in my knee" and then I tried to pull it out and found it it did...

Another typical method of getting your finger is to have your hand holding the corner and the staple, instead of going straight, hits a knot and comes right out the side into your finger...

Re: Wrong answer

I make my own boxes and frames and still can't figure out why anyone uses nails in either boxes or frames. I use 1" pine, snug tolerances, and Titebond III only and haven't had a problem for two years. When will I discover that I should have used nails?

Nail-Gun injuries to the hand.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2586285/
Most accidents involving nail guns result from operator inexperience, lack of knowledge, inattention to safety precautions, or poor mechanical safety mechanisms of the nail guns.17,22,44 Injuries occur from various circumstances, including nail ricochet, gun double firing, accidental discharges, and penetration of the receiving structure.3,17,22,38,44 Nail guns should be used only by knowledgeable, educated, and experienced personnel, with proper protective clothing, and precautionary measures should be clearly displayed at all times.36 Unfortunately, the incidence of industrial hand injuries remains high despite advances in health and safety awareness. Some studies have questioned the adequacy of on-the-job training and suggested more extensive operator training and improvement in protective clothing.13,45

Revision nail-gun safety mechanisms and use of newer sequential triggers may prevent accidental misfires. The older and more commonly used contact trip trigger nail guns allow nails to discharge from the tool anytime the nose and trigger mechanism are both depressed.13,17,22,44 Accordingly, the operator may keep the trigger depressed during rapid fire “bounce” nailing and may accidentally contact the steadying hand or other body part in lieu of the structure itself. Sequential trigger nail guns, on the other hand, require the nose of the nail gun to be depressed first—before the trigger is pressed—to fire a nail, which makes it more difficult to unintentionally discharge nails. Lipscomb et al studied 772 apprentice carpenters, carpenters with four or less years of experience, finding that approximately half of these carpenters would sustain a nail-gun injury before they completed their 4-year apprenticeship training.44 It was also not uncommon for them to be injured more than once by a nail gun during this period. Exposure to tools with contact trip trigger mechanisms carried twice the risk of injury than did tools with sequential triggers after adjusting for training and experience.44,45 Of the injuries noted, more than 40% of the contact trip injuries occurred when the carpenter was “bounce” or “bump” nailing. Although contact trigger use may not be the sole contributing factor, an increased likelihood of injury due to reduced control of accuracy is inevitable.
Lets be careful!
